Spherocytosis

Definition

Spherocytosis is a condition that causes an abnormality in the red blood cell membrane. While healthy blood cells are shaped like flattened, indented disks, these abnormal membranes lead to sphere-shaped red blood cells, and the premature breakdown of those cells.

Red blood cells suffering from spherocytosis are smaller, rounder in shape, and more fragile than healthy red blood cells. The rounded shape causes the red blood cells to be caught in the spleen, where they break down.

Spherocytosis cases may be very mild, with minor symptoms, or very severe with symptoms that quickly surface. These symptoms may occur after certain types of infections. Severe cases may be diagnosed in childhood, while those with mild symptoms may not be diagnosed until into adulthood.

Surgery

Surgical removal of the spleen can cure the anemia. The abnormal shape of blood cells remain, but the blood cells are no longer destroyed in the spleen.

Currently,
meningococcal,
Haemophilus, and
pneumococcal
vaccines are administered several weeks before splenectomy. Lifetime penicillin prophylaxis is recommended after surgery to prevent dangerous infections. The surgery is not recommended for children under 5 years old. There is a lifetime risk of serious and potentially life threatening infections.

Prevention

Because spherocytosis is an inherited condition, it is not possible to prevent the disease. Regular screening of individuals at high risk, however, can prevent the risk of complications of the disease with early treatment.
